Highline and Grand Valley Diversion were subtracted. <br />Land Ownership Status <br />A team3 composed of fisheries and realty experts contacted landowners <br />who owned bottomlands along the Green, Colorado, and Gunnison rivers in August <br />and September 1994 to discuss options for acquisition, lease, or easement. <br />Either on-site visits or telephone contacts were made with landowners of the <br />sites that were initially selected for hydrology screening. For the Green <br />River, these bottomland sites included the Meril Snow Ranch, Little Stewart <br />Lake, Baeser Bend, Brennan Bottom, and Pariette Draw. For the Gunnison River, <br />these bottomland sites included Johnson Boy's Slough and Confluence Park. For <br />the Colorado River, Adobe Creek, Griffith's, Clifton Sanitation No. 1, Pike'-s, <br />and Battlement Mesa. During each visit, team members explained the purpose of <br />the Recovery Program for the Endangered Fishes of the Upper Colorado, <br />distributed the pamphlet entitled, "Swimming Upstream: The endangered fish of <br />the Colorado River", and provided a prepared statement of commonly asked <br />questions with answers (see Appendix A). <br />Permission to access private property was requested to collect <br />additional biological data, conduct on-site screening for contaminants, and to <br />acquire river channel and bottomland profile survey data. A Right-of-Entry <br />Permit form was developed for signature to all parties for legal purposes (see <br />Appendix A). <br />RESULTS AND DISCUSSION <br />Photographic Data <br />Prior to 1993, there were few sources of up-to-date photographic <br />coverage that temporally and spatially covered warmwater reaches of the Upper <br />Colorado River Basin. Most available maps, photographs, and videos were <br />either confined to the main river channel and did not include adjacent <br />floodplain and bottomland areas or were too small in scale to be useful in <br />determining areas that would be inundated. A complete set of high-altitude, <br />infrared photographs would have been the preferred imagery for this survey <br />because they were scaled and easiest to interpret, but were too expensive. <br />A plan for complete and partial inventories of the Upper Colorado River <br />Basin is presented in Appendix C. The videography could not be used because <br />it was taken only for specific stream reaches and did not provide consistent <br />information useable for the entire bottomland survey. <br />Over 2,000 color 35-mm slides were taken during four low-level <br />reconnaissance photography flights over bottomland habitats in the Upper <br />Colorado River Basin. These photographs are documented and stored in binders <br />at the Colorado River Fishery Project offices in Vernal, Utah (Green, Yampa, <br />---------------------------------------------------------------- <br />3 The Green River team consisted of David Irving, FWS, Dave Webster. NRCS, and Doyle Dow, BR. The Colorado <br />River team consisted of Bob Burdick, FWS, and Doyle Dow. <br />14
